AUTOMATIC WEATHER STRIP.

Application filed January The present invention relates to weather strips, particularly adapted for swinging doors and windows. However, the invention is not limited for use in connection with the doors and windows of this type.

rlhe object of the invention is the provision of means for automatically projecting a strip into engagement with the door or window frames, or into engagement with the sill, when such door or window is closed and to automatically retract said strip when the door or window is opened.

It is the further object ot the invention to produce a weather strip ot the above stated character which is economical to manu- Yfacture and simple to assemble and apply, with parts insuring deiinite and positive operation.

lVith the above and other objects in view the invention further resides in sundry details ot construction, combination, and arrangementot parts hereinafter mo-re 'fully described and pointed out in the appending claim-s.

In the drawings which show the pre-l ferred embodiment as at present devised:

Figure l is a fragmentary elevation of the swinging door or window, equipped with the weather strip oi the present invention,

Figure 2 is a vertical section through the' door or window as shown in Figure l,

Figure 3 is a horizontal sectional view through the weather strip,

Figure at is a :side elevation ot one ot the casing sections of the weather strip with the enclosed parts indicated by the dotted lines,

Figure 5 is a side elevation of the other casing section oi the weather strip with the enclosed operating parts indicated with dotted lines, and

Figure (i shows a side elevation o'lE the completed weather strip.

Referring particularly to the drawings:

i. denotes a door or window to which the device is attached, the door or window having a panel t and being mounted to swing ou the hinges 7 secured to the usual traine (i. On the upper and lower edges of the door or window is secured the weather strip ot the present invention, whichv comprises a easing composed ot two complemental elongated channeled strips 30 and 81, one designed to slide within the other to form an extensible casing. The end Wall oit the strip 3l is provided with a weather strip of felt, rubber or other material to engage with a 6, 1926. Serial No. 79,667.

sill 3, or other surface of a door or window j amb or frame, to form a tight contact therewith. Suspended from the end wall ot the casing member 30 are brackets lO which receive the ends of the reciprocable rods l2 deposed in the casing. The rod may be additionally supported by rollers 19 mounted in a guideway l1 in which the rod l2 reciprocates.

The rod l2 has at .spaced intervals openings or recesses 2l provided therein in which one arm of the bell-crank levers 14 engage, respectively. These bell-crank levers le are disposed within the casing formed by vthe channel strips 30 and 3l, but are supported on pivot pins which extend tl'irough transverse elongated slots 2O in the side walls of the inner casing member 3l and mounted at their ends in the side walls oit the casing member 80. Thus, by this construction the casing members are held in assembled position and the elongated slots 2Ov permit the casing to telescope one within the other to produce the desired expanding and retracting movement for the purpose of this device.

The other arm of the bell-crank levers 14 extend under a stop rod or pin 1G and are designed to engage the bow-leaf spring 15, one arranged adjacent each of said bell crank levers lst and pivotally supported at one end to the bottom wall of the inner casing member 3l.

The weather strip ot this invention is designed to be inserted within a suitable groove provided in the edges ot the door, as shown in Figures l and 2, and the outer casing 8O `has its free ends bent laterally outward to provide flanges 32 which will receive nails or screws.

The weather strip above described is actuated by an adjustable presser head 5 forming a threaded extension from one end of the rod 1,2, preferably the end ot the rod adjacent the hinge edge ot the door or window. The coil springs 9 on the redilced ends oi the rod i2 bear against the stationary brackets l() to move and retain the operating parts of the weather strip in. released or ineffective position. It will be obvious that as a door 0r window, equippedl with the present invention, is closed the pressed head 5 will contact with the jamb and shift the reciprocating bar l2 against the action of the springs 9 and thereby swing the bell crank levers 14- so as to compress the springs 15, which ac- -ment 4C engages.

tion will force the member' 31 of the Casing outwardly against the opposing Wall of the dooror Window jamb or sill., The springs l5 acted on by the bell Crank levers will produce a tight yielding Contact with the surtaee which the packing or Weather strip elelt will be observed and appreciated that the present invention can also be used upon the side edges oi' doors and Windows by providing the presser `head 5 with a'beveled or Chan'ipiered surface or permit the same to engage with an inclined surface.'

V,The Weather strip of `the present invention is a 4Compact unitary device 'which' may be readily applied as a unit in a groove oit' a door or Window as the parts are permanently assembledtogether 'and' contained in an ein tensible easing` or housing.

Having thus described my invention, What isv elaimedis:

`lpfirin lautomatie weather strip for doors and Windows eoi'nprisin'g 'a easing of elongated Vcomplemental members, one adapted to'finove transversely with respect tothe other, a slidable bar Within the-casing and mounted longitudinally on one of the members, meansior normally urging said bar to move in edgeivise direction, a bow-leail spring within'the casing having one end'secured to the bottom` oi' the other easingl meniber, a bell-Crank lever mounted Within the easing Vand having one arm engaging an abutment on said bar and the other arm engagingsaid spring member, a' presser head on lsaid bar andnormally extending beyond an end of said casing to engage with a j amb of a door or Window, whereby the movable members of said Casing will be moved ont- Wardly when ythe door or Window is closed.
